The PT-RZ670BU is commercial projector that offers features and performance that are well up to most tasks. It's well suited for use in large venues, trade shows, multi-projector based high-impact specialized commercial applications, and with its DICOM Simulation mode, for medical classroom/training applications.
If offers natural looking colors and even its brightest picture mode is still good enough for many applications.
It is a big and heavy projector, under 50 pounds without the lens (and just over 50 lbs. with the supplied zoon lens), that appears to be ruggedly built and should offer reliable service for a very long time, even with heavy 24/7 use.
Job well done!
